A forward-backward motion estimation method in frame rate up conversion for video applications comprising the steps of; updating a forward motion vector field (MVF_fw) and a backward motion vector field (MVF_fw) using a recursive search method, merging updated vector fields (MVF_fw_upd, MVF_bw_upd) by selecting motion vector field which has minimum sum of absolute difference value and by adding a smoothness parameter, which is a vector field that depends on selected vector field. In this method, neighbour blocks of the block to be updated are used to calculate smoothness parameter. Thus, by this method a smoother motion vector field is generated. |
